Pricing is pending confirmation. Offers, device availability, taxes, fees, term commitments, and eligibility must be confirmed with our team. Internet services vary by address.
Fiber or Cable: know the difference.
AT&T Fiber · Fiber to your home
Fiber runs directly to the premises. Upload and download speeds are typically equal or similar. A good option to consider for video meetings, cloud backups and large file uploads.
Xfinity · Cable Internet
Typically uses a fiber-coaxial network, with coaxial cable for the final connection to the premises. Download speeds are often higher than upload speeds; available upload speeds depend on your address and plan. Suitable for everyday browsing, streaming and downloads.
Actual technology, speed, pricing and availability depend on the service address and selected plan. Xfinity offers additional technologies in some areas. Residential fiber is not the same as a dedicated business connection; both fiber and cable networks may share upstream capacity.
Check Internet availability ↗Two ways to find your next plan.
Major carriers | Contract · New phone
Phone costs are paid in installments, with eligible device offers applied as monthly credits according to the plan. For customers who want to upgrade to a new phone.
Smaller providers | No contract · Lower monthly cost
Keep your current phone and use the same three major wireless networks. For customers looking to reduce their monthly service bill.
These describe the two categories of plans offered by our store. Actual contract, financing and offer terms depend on the selected plan. Early cancellation may require paying the remaining device balance and may end future credits. Coverage, data priority, hotspot and international services vary.
